MACHINE FOR TURFING FABRICS.

SPECIFICATION forming part of Letters Patent No. 269,770, datedDc-cember 26, 1862,

Application filed December 6, 1881. (No model.) i

terial-througii the cloth, leaving the ends free and protruding.Thisprocess, known as turfi'ng, has been employed with.very beneficialresults in the making of mittens and similar articles of apparel, andadds greatly to the warmth and wearing qualities of said articles; butas heretofore accomplished by hand it is a very tedious operation, andso much time is consumed in the making of the articles as to render themvery expensive. My object is therefore to provide a machine whereby theoperation of turling may be rapidly and accurately performed, and thuscheapen fabrics of this class. This object I attain by the mechanismshown in the accompanying drawings, which form a part of thisspecification, and in which- Figure 1 is a side elevation of my machine;Fig. 2, a front elevation of the head of the same. Fig. 3 is a sectionalelevation of the head; Fig.4,a si'mi-lar view, showing the needle in adifferent position. Fig. 5 is a detail view of the cam-grooves andtoothed rack which operates the threading device, shown as developed ona straight line, and also showing a section of the same at the upperpoint of intersection of the grooves. Figs. 6, 7, 8, and 9 are detailedviews of the threading device, referred to hereinafter; and Fig. 10, aview showing the manner in which'the yarn is looped through the fabric.

, Similar letters refer to similar parts throughout the several views.

In the drawings, A represents the table of the machine, on which is themain frame B. Secured to the under side of the table A are bearings b b,in which is supported a shaft, Gr, carrying at one end a wheel, F,provided on its inner side with a grooved wheel or pulley, H, to whichthe power to drive the machine is supplied by means of a belt from anyconvenient source.

0n the outer face of the wheel F is a crankpin, a, to which is connectedone end of a pitman, E, connected at its other end to a lever,

D, pivoted at p to the main frame B, and provided at its outer end witha block or pin, D, which is bifurcated at one end and connected by apin, 61, to the needle U, which reciprocates vertically in bearings band b on the head B 6o of the main frame B. The block D slides into theend of the vibrating lever I), which is bored out-to receive it, and isthus enabled to adjust itself longitudinally to permit the needle 0 tomove or reciprocate vertically, whilezh end og u of the vibrating leverD describes the arc of a 7 circle. The needle O for the'greater portionof its length is made round, but is bifurcated at the lower end, formingtwo prongs, e and 0,

each of which is pointed and provided with an eye, 6 These eyes 6 areformed on one edge of the prong, as shown'in Fig. 4, and are partiallyopen on one side. They are so arranged on the edges of the respectiveprongs as to be closed by the lower forked end of part a of the needlewhen said part a is depressed, as shown in Fig. 3. The upper portion ofthe needle 0 is composed of two parts a. and a, in the one, a, of whichis a round hole, in which fits the pin d, which connects it with theblock D,

while the other part, a, is provided with a slot, 0, which allows aslight vertical movement of the pin (Z and part a of the needle 0, whilethe part a remains at rest. A spring, a, at the upper end of the needle,one end of which rests against a collar, 0, on the part a, and the otheragainst a shoulder, a, on part a, serves to hold the parts a and atogether, with the pin d at the lower end of the slot 0 and the eyes 0of the needle closed, as shown in Fig. 3.'

Pivoted atg to the head Bot'the main frame B is a lever, O, the end 0 ofwhich is bent at right angles and carries the threading device,hereinafter more fully described, the other end being connected by aconnecting link or rod, 9

L, to the block'D.

P is a threading-disk, which is provided at one side with a pinion, h.This disk is provided with prongs, shaped as shown in Fig. 7,

and turns on a stud, i, which is shouldered at one end, and afterpassing through a slotted opening, j, in the arm 0 is screwed at theother end into a sliding piece, Z, working in slides Z on the arm 0.

Secured to the stud i, between the disk P and the arm by a smallset-screw, i (see Fig. 9,) is a collar, i provided with notches idiametrically opposite each other, with one of which a pawl or slidingbolt, it, working in lugs 12. and n on the side of the disk P, andpressed forward by a spring, n pressing against a collar, a on the boltk, engages at each half-revolution of the disk P, which is thus heldtemporarily at rest. The disk P is prevented from turning backward bythe peculiar shape of the end of the bolt k and the corresponding notch,i, each of which has one side beveled ofi, as shown, whereby said boltis forced back and out of the notch when the disk is turned forward.

Around the edge of the disk P, which consists properly of a number ofprongs, provided with a V-shaped groove, V, is wound the yarn ormaterial with which the turfing is done preparatory to being put' intothe needle, in the manner hereinafter set forth. In a slot, 1?, at eachend of the disk P is pivoted a knife, t, the edge of which stands justbelow the yarn when wound around the disk. The lower end of the head Bis rounded off on one side on the arc of a circle struck from the point9 as a center, and is provided with a recess, J, on one side of whichare a. number of teeth, m, with which the teeth of the pinion h on thedisk P engage, and of which there is a sufficient number to turn saiddisk one-half of a revolution.

In the bottom of the recess J are two camgrooves, r and 7", which cometogether in the points a: and at above and below the line of the teethm,the one, 1-, beingstraight and the other, r, curved. These cam-groovesgradually increase in depth throughout their length, the one 1' havingits deepest point at m and the one a at av. In these grooves 0- and 1"works a pin, 1' fitted in the end of the stud i, which is bored out andsupplied with a spring, 1', against which the end of the pin 1' tests,and which tends to keep said pin forced outward and against the-bottomof the cam-grooves r and r.

R is the yarn, which is held on a spool, S, which sets on a spindle, T,on the main frame B, and extends through the eyes a, u, and a and iswound partly around the disk P, as shown in Fig. 7, the end beingpressed firmly into and held by the groove V.

The operation is as follows: The yarn having been placed in the disk P,as described,

with the needle and disk in the relative positions shown in Fig. 3, thewheel F is turned a half of a revolution, thus bringing the needle G tothe upper limit of its stroke. The part a on striking the projection orstop f is retarded, while the part a is carried on, thereby opening theeye 0 of the needle, as shown in Fig. 4. The disk P is at the same timecarried down by the lever 0. The pin 0' in the bottom of the stud *5moves in the cam-groove 0", and throws the disk over until the teeth ofthe pinion h clear those on the side of the recess J and brings aprojection, t, on the knife t in line with a lug, m, on the head B, thuscausing the knife to sever the yarn. The disk P is held from turning bythe bolt k, engaging with the notch t" in the collar 1' on the stud 'i,and is carried forward until the piece of yarn It, which in the meantimehas been cut 011' from the supply by the projection t of the knife tstriking the lug m, is brought into the eye 0 of the needle 0 at thepoint y. It will be seen that the projection t coming in contact withthe lug m, causes the knife to close, thereby cutting the yarn. The workor material to be tut-fed is now placed on the table under the needle,and the machine started. As the lever D starts down the eyes of theneedle are closed on the piece of yarn R by the spring 0, beforedescribed, the lever O and disk P remaining stationary during thisoperation on account of the arm or link L being slotted where itconnects with the lever 0. As the needle descends the piece R (of yarn)is pulled from the disk and carried .down, and the two ends carriedthrough the cloth or other material by the prongs e and e of the needle.As the needle continues to descend the ends of the yarn are drawn fromthe eyes of the needle, and remain in the cloth or other material whenthe needle is withdrawn. The disk in the meantime, carried by the leverO, operated by the link L from the block D, has returned to its formerposition. During this return movement the pin T2, following thecam-groove 1, causes the pinion h to engage with the teeth m, and turnsthe disk a halt revolution, winding the yarn on the other side, ready tobe put into the needle, as before set forth. The cloth or other materialis moved slightly at each stroke until the whole surface is covered orturi'ed, a piece of yarn being out 01f, placed into the needle, andlooped through the cloth or other material at each revolution of thewheel F.

\Yith this machine the material for a pair of mittens, or for a hood,may be turfed in a few minutes, which would require by the old methoddays of labor.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-- 1. A threading-disk,P, provided with a cuttcr or cutters, t, whereby the yarn or equivalentis cut in lengths preparatory to threading, substantially as describedand shown.
